본 고안은 자동차 공기조화기의 관접속장치에 관한 것으로서, 특히 관접속부의 밀폐성이 높음과 동시에 배관작업이 용이할 뿐만 아니라 관접속작업시간이 단축되는 자동차 공기조화기의 관접속장치에 관한 것이다.The present invention relates to a pipe connecting device of an automobile air conditioner, and more particularly, to a pipe connecting device of a car air conditioner that not only has a high sealing property, but also facilitates piping work and shortens the pipe connection work time.
차량용 에어컨은 제1도에 도시한 바와 같이, 냉매 및 공기의 순환에 의해 차량내부를 냉방한다.As shown in FIG. 1, a vehicle air conditioner cools inside a vehicle by circulation of a refrigerant and air.
즉, 압축기(1)로부터 토출된 고온 고압의 냉매가스가 응축기(3)에서 팬(5) 등에 의해 강제냉각되어 액화되고, 액화된 냉매는 리시버 앤드 드라이버(7)에서 수분과 이물질이 제거된 후 팽창밸브(9)내에 유입된다.That is, the refrigerant gas of the high temperature and high pressure discharged from the compressor 1 is liquefied by being forcedly cooled by the fan 5 in the condenser 3, and the liquefied refrigerant is removed from the receiver and driver 7 by moisture and foreign matter. It flows into the expansion valve 9.
상기 팽창밸브(9)내에 유입된 고압의 냉매액은 상기 팽창밸브(9)의 단열팽창효과에 의해 저압의 안개상태의 냉매로 변환되어 증발기(11)내에 유입되고, 상기 증발기(11)내에 유입된 안개상태의 냉매는 블로아(13)에 의해 주위의 공기와 서로 열교환되면서 냉매가스로 변환되며, 상기 열교환된 냉매가스는 상기 압축기(1)에서 고온고압의 냉매가스로 변환되어 위에서 설명한 사이클을 반복한다.The high pressure refrigerant liquid introduced into the expansion valve 9 is converted into a refrigerant in a low pressure fog state by the adiabatic expansion effect of the expansion valve 9, and then flows into the evaporator 11 and flows into the evaporator 11. The refrigerant in the fog state is converted into the refrigerant gas by heat exchange with the surrounding air by the blower 13, the heat exchanged refrigerant gas is converted into the refrigerant gas of the high temperature and high pressure in the compressor (1) to perform the cycle described above Repeat.
이때, 차실내의 온도를 감은통(15)으로 감지하여 모세관(17)을 통해 팽창밸브(9)를 조절하므로써, 상기 팽창밸브(9)의 개폐정도를 증감하게 된다. 그리고, 상기 블로아(13)에 의해 유동력이 증가된 차실내의 공기는 상기 증발기(11)를 지나면서 냉각되어 차실내를 순환하는 것이다.At this time, by controlling the expansion valve (9) through the capillary tube (17) by sensing the temperature inside the vehicle compartment, the opening and closing degree of the expansion valve (9) is increased or decreased. In addition, the air in the vehicle compartment in which the flow force is increased by the blower 13 is cooled while passing through the evaporator 11 to circulate the interior of the vehicle compartment.
그리고, 상기 응축기(3)와 증발기(11)의 각 입출구부등에는 상기 응축기(3)와 증발기(11) 등을 용이하게 설치하도록 냉매관에 접속되는 관접속장치(19)가 배설되어 있다.In each of the inlet and outlet portions of the condenser 3 and the evaporator 11, a pipe connecting device 19 connected to the refrigerant pipe is provided to easily install the condenser 3, the evaporator 11, and the like.
종래의 자동차 공기조화기의 관접속장치는 제2a도 및 제2b도에 도시한 바와 같이, 응축기 또는 증발기(이하 열교환기라 한다)의 튜브에 연통한 냉매출입관(23)의 단부에는 이음본체(25)의 일단부가 용착되고, 상기 이음본체(25)의 타단부에는 냉매관(27)이 너트(29)에 의해 밀착접속되며, 기밀을 유지하도록 상기 냉매관(27)의 단부의 외주면과 상기 너트(29)의 내주면사이에는 슬리이브(31)가 삽입배설된 구조로 되어 있다.As shown in FIG. 2A and FIG. 2B, the connection device of a conventional automobile air conditioner has a joint main body at an end of the refrigerant inlet pipe 23 communicating with a tube of a condenser or an evaporator (hereinafter referred to as a heat exchanger). One end of the coolant pipe 25 is welded to the other end of the joint body 25, and the coolant pipe 27 is tightly connected by the nut 29, and the outer circumferential surface of the end of the coolant pipe 27 is maintained to maintain airtightness. The sleeve 31 is inserted and disposed between the inner circumferential surfaces of the nut 29.
상기 이음본체(25)의 일측단부의 내주면에는 상기 냉매출입관(23)이 이음본체(25)내에 일정량 삽입되어 걸리도록 걸림단(25a)이 형성되어 있고, 그 타측단부의 외주면에는 상기 너트(29)가 나사결합되도록 숫나사가 형성되어 있으며, 그 타측단부의 단면에는 상기 냉매관(27)이 용이하게 밀착하도록 경사면이 형성되어 있고, 그 중앙부의 외주면에는 스패너 등의 공구로 죄기가 용이하도록 육각면부(25b)가 형성되어 있다.A locking end 25a is formed on the inner circumferential surface of one side end of the joint body 25 so that the refrigerant access pipe 23 is inserted into the joint body 25 by a predetermined amount, and the nut (on the outer circumferential surface of the other end of the joint body 25) is formed. The male thread is formed so that the screw 29 is screwed together, and an inclined surface is formed on the end surface of the other end thereof so that the refrigerant pipe 27 is in close contact with each other, and the outer circumferential surface of the center portion is hexagonal for easy clamping with a tool such as a spanner. The surface part 25b is formed.
상기 냉매관(27)의 단부에는 상기 이음본체(25)의 경사면에 용이하게 밀착하도록 나팔형의 플레어부(27a)가 형성되어 있다.A flared portion 27a of a trumpet shape is formed at an end of the coolant pipe 27 so as to easily contact the inclined surface of the joint body 25.
상기 너트(29)의 일측단에는 상기 슬리이브(31)를 걸어 상기 냉매관(27)의 플레어부(27a)의 외주면에 밀착시키도록 걸림단부(29a)가 형성되어 있다.A locking end 29a is formed at one end of the nut 29 so as to contact the outer circumferential surface of the flare portion 27a of the refrigerant pipe 27 by hanging the sleeve 31.
상기 슬리이브(31)의 일단부의 외주면에는 상기 너트(29)의 걸림단부(29a)에 걸리도록 돌출부(31a)가 형성되어 있다. 그리고, 상기 슬리이브(31)의 일단부의 내주면은 상기 냉매관(27)의 플레어부(27a)에 밀착하도록 라운딩되어 있다.On the outer circumferential surface of one end of the sleeve 31, a protrusion 31a is formed to be caught by the locking end 29a of the nut 29. The inner circumferential surface of one end of the sleeve 31 is rounded to be in close contact with the flare portion 27a of the coolant pipe 27.
이와 같이 구성된 종래의 관접속장치의 접속방법은 다음과 같이 행해진다.The connection method of the conventional pipe | tube connection apparatus comprised in this way is performed as follows.
즉, 냉매출입관(23)을 이음본체(25)의 내부에 끼워 서로 용접결합시키는 한편, 냉매관(27)에 슬리이브(31) 및 너트(29)를 끼운 후, 원추형의 펀치를 사용하여 상기 냉매관(27)의 선단부를 나팔형으로 넓혀 플레어부(27a)로 형성시킨 다음, 스패너 등의 공구를 이음본체(25)의 육각면부(25b) 및 너트(29)의 육각면부에 끼워 서로 죄면, 상기 너트(29)의 걸림단부(29a)는 슬리이브(31)의 돌출부(31a)에 걸려 상기 슬리이브(31)는 상기 냉매관(27)의 플레어부(27a)를 밀어 상기 이음본체(25)의 경사면에 밀착시키게 된다.That is, the refrigerant inlet pipe 23 is inserted into the joint body 25 and welded to each other, while the sleeve 31 and the nut 29 are fitted in the refrigerant pipe 27, and then a conical punch is used. The tip end portion of the refrigerant pipe 27 is widened in a trumpet shape to form a flare portion 27a, and then a tool such as a spanner is inserted into the hexagonal surface portion 25b of the joint body 25 and the hexagonal surface portion of the nut 29 to each other. When tightened, the locking end 29a of the nut 29 is caught by the protrusion 31a of the sleeve 31, and the sleeve 31 pushes the flare 27a of the refrigerant pipe 27 to the joint body. It comes in close contact with the inclined surface of (25).
그런데, 이와 같이 구성된 종래의 관접속장치에서는 냉매관(27)을 접속하기 위해 냉매관(27)의 단부에 플레어부(27a)를 형성시키는 플레어형성작업을 하여야 한다는 문제점이 있었다.However, in the conventional pipe connecting apparatus configured as described above, there is a problem in that a flare forming operation for forming the flare portion 27a at the end of the coolant pipe 27 is required to connect the coolant pipe 27.
또한, 냉매관(27)의 직경이 크게 되면, 이음본체(25)의 육각면부(25b) 및 너트(29)의 육각면부의 크기가 필연적으로 크게 되어 대형의 스패너 등의 공구를 사용해야 하므로, 큰 토오크를 가해야 하는 등, 관접속작업이 용이하지 못하다는 문제점이 있었다.In addition, when the diameter of the refrigerant pipe 27 is large, the size of the hexagonal surface portion 25b of the joint body 25 and the hexagonal surface portion of the nut 29 inevitably become large, so that a tool such as a large spanner must be used. There is a problem that the pipe work is not easy, such as the need to apply torque.
또한, 경질의 플레어부 및 슬리이브에 의해 시일하므로 밀폐성이 낮다는 문제점이 있었다.In addition, there is a problem that the sealing performance is low because it is sealed by the hard flare and the sleeve.
따라서, 본 고안은 상술한 문제점들을 해결하기 위하여 이루어진 것으로서, 본 고안의 목적은 냉매출입관 및 냉매관을 플랜지와 연질의 패킹수단에 의해 서로 접속하므로써, 관접속부의 밀폐성을 높임과 동시에 배관작업을 용이하게 할 뿐만 아니라 작업시간을 단축시키는 자동차 공기조화기의 관접속장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to connect the refrigerant access pipe and the refrigerant pipe with each other by a flange and a soft packing means, thereby improving the sealing property of the pipe connection and at the same time performing the piping work. It is to provide a connection device of an automobile air conditioner that not only facilitates, but also shortens working time.

즉, 연결부시(41)의 제1관부(41d) 내측에는 냉매출입관(33)이 고착되어 있고, 제2플랜지(39)의 돌출관부(39c) 내측에는 냉매관(35)이 고착되어 있으며, 연결부시(41)의 제1관부(41d)의 외주면에는 제1플랜지(37)가 슬라이딩되어 상기 걸림턱부(41a)에 걸리고, 상기 연결부시(41)의 제2관부(41c)의 외주면에는 제2플랜지(39)의 슬라이딩부(39d)가 슬라이딩되어, 체결부재(45)를 체결함에 의해 패킹수단(43)이 압축되어 변형되어 기밀을 유지하게 되는 것이다.That is, the refrigerant inlet pipe 33 is fixed to the inside of the first pipe portion 41d of the connecting bush 41, and the refrigerant pipe 35 is fixed to the inside of the protruding pipe portion 39c of the second flange 39. On the outer circumferential surface of the first tube portion 41d of the connecting bush 41, the first flange 37 is slid to engage the latching jaw portion 41a, and on the outer circumferential surface of the second pipe portion 41c of the connecting bush 41. The sliding part 39d of the second flange 39 is slid, and the packing means 43 is compressed and deformed by fastening the fastening member 45 to maintain airtightness.
따라서, 다수의 체결수단(45)으로 상기 제1플랜지(37) 및 제2플랜지(39)를 결합하므로, 종래 대형 스패너를 사용해서 이음본체의 육각면부와 너트를 죄는 것에 비해 힘이 적게 들고, 관접속장치의 구조가 간단하며, 냉매관에 플래어부를 형성해야 하는 종래의 관접속작업에 비해 접속작업이 용이하며, 오링에 의해 기밀의 신뢰성이 있으며 관접속장치의 구조가 간단한 것이다.Therefore, since the first flange 37 and the second flange 39 are coupled to each other by a plurality of fastening means 45, the force is less than that of clamping the hexagonal surface portion and the nut of the joint body using a conventional large spanner, The structure of the pipe connection device is simple, and the connection work is easier than the conventional pipe connection work in which the flare portion is to be formed in the refrigerant pipe, the airtight reliability is reliable, and the structure of the pipe connection device is simple.
앞에서 설명한 바와 같이 본 고안에 의한 자동차 공기조화기의 관접속장치는 냉매출입관 및 냉매관을 플랜지 및 연질의 패킹수단에 의해 서로 접속하므로써, 관접속부의 밀폐성을 높임과 동시에 배관작업을 용이하게 할 뿐만 아니라 작업시간을 단축시킨다는 매우 실용적인 고안이다.As described above, the pipe connecting device of the automobile air conditioner according to the present invention connects the coolant access pipe and the coolant pipe to each other by flanges and soft packing means, thereby increasing the sealing property of the pipe connection portion and facilitating piping work. In addition, it is a very practical design to shorten the working time.
